is an important protozoan parasite that can infect a range of animals. Cats are the most important definitive hosts for . Therefore, an assessment of the level of infection in cats is of public health importance. As limited information about seroprevalence of infection in cats in northeastern China was available, 854 serum samples, including 235 cats in Jilin province, 267 cats in Liaoning province, and 352 cats in Heilongjiang province, were examined by an indirect hemagglutination assay (IHA) test, between September 2013 and July 2019. The overall seroprevalence of was 19.09% (163/854) at the cutoff 1:64, with 19.60% (69/352), 18.29% (43/235), and 19.10% (51/267) in Heilongjiang, Jilin and Liaoning, respectively. Logistic regression analysis showed that mode of life was highly related to infection in cats at the investigation areas. These results could provide foundation data for prevention and control of prevalence in these regions. Moreover, the results also suggested that the effective control strategies should continue to be performed.
是一种重要的原生动物寄生虫，可感染多种动物。猫是旋毛虫的最重要的终末宿主。因此，评估猫旋毛虫感染水平具有重要的公共卫生意义。由于东北地区猫旋毛虫感染的血清学流行率的信息有限，本研究于 2013 年 9 月至 2019 年 7 月，采用间接血凝试验（IHA）对 854 份血清样本（包括吉林省 235 份、辽宁省 267 份和黑龙江省 352 份）进行了检测。在截断值为 1:64 时，总血清阳性率为 19.09%（163/854），黑龙江、吉林和辽宁的阳性率分别为 19.60%（69/352）、18.29%（43/235）和 19.10%（51/267）。逻辑回归分析表明，生活方式与调查地区猫旋毛虫感染高度相关。这些结果可为这些地区预防和控制旋毛虫流行提供基础数据。此外，结果还表明应继续采取有效的控制策略。
